Gamblers spent $20.2 million at Horseshoe Casino Cincinnatiin March – down 4 percent from March last year, the casino’s debut month.

Revenue results released Monday show that while the Cincinnati casino’s business declined, it did so at a lower rate than statewide totals.

Ohio’s four casinos generated $79.6 million in March – down 5.6 percent from the same month a year ago. Lower casino revenue in Ohio means less tax revenue to local governments and schools, which collect most of the state’s 33 percent casino tax.

Revenue dropped 13.1 percent to $21.3 million at Cleveland’s Horseshoe casino. Suburban Cleveland has two new racinos, ThistleDown, which opened last spring, and the Hard Rock Rocksino, which opened in December.

The Cincinnati Horseshoe’s latest competitor is Miami Valley Gaming, which opened in December in Turtlecreek Township. More competition is coming: Belterra Park, the former River Downs, is set to open May 1 in Anderson Township.

It will become the region’s sixth gambling destination with 1,500 video slot machines and a rebuilt thoroughbred race track. Belterra Park also will have three sit-down restaurants, three snack or beverage outlets and event space.
